SEAM-PRESSER.

sPEcIFIcA'rIoN formmg part of Letters Patent No. 261,459, aatea July 18, 1882, Application filed April S, 1882. (No model.)

.To all whom it may comem Be it known that we,JosHUA` GHAsE J ELLI- soN and WINFIELD SMITH, both of Portsmouth, in the county of Rockingham and State of New Hampshire, have invented` certain new and useful Improvements in Seam-Pressers; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to Which it pertains to make and use the same.

Our invention relates to an improvementin machines for the manufacture of shoes, and more particularly to that class th ereof designed for pressin g seams, the object being to provide a machine of this character which shall coinbine simplicityof construction and ease of operation With durability and efficiency in nse.

I With this end in view our invention relates to certain details of construction and combinations of parts, as will be hereinafter described, and pointed out in the claims.

In the accompanyingdrawiugs, Figure 1 represents a seam-pressing machine constructed in accordance with our invention. Fig.2 is a detail view, in perspective, of the guiding devices; and Fig. 3l is a view in vertical section through the peripheries of the pressing wheel and disk.

The bed-plateA is designed and adapted to be secured to a bench or any other suitable support. It is provided with avertical standard, B, which supports the journal-hearing O, and With a sleeve, D. One end of the shaft E, which is journaled in the hearing O,is provided with a drive-wheel, F, the other end of the shaft having a disk, G, attached to it. The said disk G is formed with a concaved periphery, the deepest portion of the concavity being milled. A reciprocating spindle, H, is mounted in the sleeve D. A wheel, I, having a eo'nvex periphery adapted to be received Within the periphery of the disk G, is mounted in the upper end of the said spindle H, the lower end of the same being attached-to a rod, J, Which is also connected with a perforated lug, K, formed on one side of the treadle L, pivotally supported between two suitable standards, M, located below the bench to Which the bed-plate A is se- V cured. A nut, N, prevents the rod J from being withdrawn from the lug K when the heel of the treadle is depressed,while a spiral spring,

O, encircliug the rod and interposed between the upper face 'of the said lug and a pin, P, secured to the said rod, sustains the lug and nut aforesaid in a state of normal engagement.

v In connection with the disk and wheel above describedflwe employ. devices for guiding the work, and they consist of the guiding-finger Q and the plate R, the contour of the inner face of which conforms with the shape of the end of the guiding-finger. The said guiding-finger is rigidly secured'to the reciprocating spindle H, while the plateR is secured to an arm Which is secured to the hearing B.

Having described'the construction of ourdevice, we will now set forth its method of operation.

The disk G is rotated by power imparted to the driver-wheel F. If now the toe of the treadle is depressed, the rod J and spindle H will be elevated through the mediumship of the spring O. As the wheel approaches the diskthe article the scams of which it is desired to press is interposed between them in such mannerthatits seamed portion Will beincluded between the disk and wheel and the finger and plate of the guiding devices; and inasmuch as the article is forced into an intimate relation With the milled surface of the disk which revolves, it is fed by the same through the machine, being guided and creased by the finger Q and the plate R.

lt will be observed that the wheel I is held in place by the spring, and therefore if any double scams or any unusual thicknesses of leather are brought between the disk and wheel the latter will be depressed snfticiently to permit such double seam or thickness to pass Without interfering with the action of the machine. The extentor degree of the com pression of the seams will depend upon the force with which the wheel I is sustainedin' its elevated position, and as this depends entirely upon the will of the operator of the machine, he is enabled, by varying the pressure upon the treadle, to regulate the compression of the sea-ms and produce any and all ei'ects within the scope of the machine. p

It is'apparent that in meeting the requiremente of the Ordinary practical conditions it may be necessary to make some changes in the construction of our machine. We would there- IOO fore have it understood that we do not limit ourseives to the exact construction shown and described, but that we ho'sd ourselves at liberty to make such alterations as fairly fall Within the spirit and scope ot' our invention.

Having fully described our invention, what we claim as new, and desire to secure by Letters Patent, is-

1. In a seam-presser, the combination, with adisk having a concaved periphery constructed with its deepest portion miiled and with sniooth sides, of an adjustahle wheel having a convexed periphery, substantially as and for the purpose set forth.

2. In a seam-presser, the combination, with a disk having a concaved periphery, of a Wheel having a convexed periphery, a spindle in the upper end of which said wheel is mounted,and

devices to elevate the spindie and bear the pez riphery of the Wheel against that of the disk. 2o

3. In a seam-presser, the combination, with a disk having a concaved periphery,of a wheel having a convexed periphery, a spindle in the upper end of Which the wheel is mounted,an(l devices to apply foot-power to the spindie to 25 elevate it and bear the periphery of the Wheel against that of the disk.

In testimony whereof We have signed this specification in the presence of two subscribing wituesses.
